|Used By||Sōjirō Kusaka|
The Ōin (王印, King's Seal) is an artifact that belongs to Soul Society's Royal Family, and is moved from its storing place to another every few decades.
When the ōin was being transported to a new location. Sōjirō Kusaka and his two Arrancar companions attacked the transport and stole the artefact, despite 10th Division captain, Tōshirō Hitsugaya, guarding the transport. Later on Kusaka tries to get Hitsugaya to stab the ōin with his Bankai, so its power would be released, but Hitsugaya refuses and Kusaka himself cuts the artefact. Because of this, Kusaka turned into a large, powerful ice dragon, but very unstable due to Kusaka not having achevied Bankai. It took the effort of several captains and Ichigo Kurosaki, but Kusaka was eventually defeated. Afterwards the ōin was returned to the state it was in prior to being cut by Kusaka.
